Are ADUs in Los Angeles Subject to Rent Control? Complete Guide for Property Owners

Accessory Dwelling Units (ADUs), commonly known as granny flats, in-law units, or backyard homes, have become a major housing solution in Los Angeles. With California's housing crisis driving demand for additional rental income, many homeowners are considering ADU construction. However, understanding rent control implications is crucial before breaking ground or signing lease agreements.

Understanding Los Angeles Rent Control Laws

Los Angeles operates under the Rent Stabilization Ordinance (RSO), which applies to most multi-family properties built before October 1978. The RSO caps annual rent increases and provides tenant eviction protections. For ADUs, rent control application depends on the unit type, construction method, and the age of your primary residence.

Detached ADUs: Generally Exempt with Important Exceptions

New detached ADUs are typically exempt from RSO rent caps, even when built on properties with pre-1978 main houses. This exemption makes detached units attractive for rental income generation.

However, there's a critical caveat: if you rent out both the detached ADU and a pre-1978 main house simultaneously, the entire property becomes subject to RSO rent control. This occurs because the property now functions as a multi-family rental, triggering RSO coverage for the main residence that was previously exempt as owner-occupied.

Attached and Converted ADUs: Complex Rent Control Scenarios

Attached ADUs

When you build an attached ADU onto a pre-1978 single-family home, rent control implications become more complex. The Costa-Hawkins Rental Housing Act may exempt the new ADU from rent caps, but eviction protections under the RSO will still apply. Additionally, adding an attached ADU may trigger RSO coverage for the main house.

Converted ADUs

Converting existing space within a pre-1978 home into an ADU subjects both units to full RSO coverage. This includes garage conversions, basement apartments, or repurposed rooms. Both the converted ADU and original residence will be subject to rent caps and all RSO tenant protections.

Just Cause Ordinance (JCO) Protections Apply Citywide

Even when ADUs are exempt from RSO rent caps, Los Angeles's Just Cause Ordinance (JCO) still applies to all rental units. Under JCO, landlords must provide valid legal reasons for evictions and may be required to pay relocation assistance to displaced tenants. Valid reasons include non-payment of rent, lease violations, or owner move-in situations.

Statewide Rent Control Under AB 1482

California's Tenant Protection Act (AB 1482) adds another layer of rent control consideration. ADUs built before 2005 may be subject to statewide rent caps of 5% plus local Consumer Price Index annually, regardless of local rent control exemptions. This state law also provides just cause eviction protections for tenants in qualifying units.

Geographic Considerations: Los Angeles vs. Surrounding Areas

Rent control laws vary significantly across Los Angeles County. While the City of Los Angeles has comprehensive RSO protections, many surrounding cities like Beverly Hills, Santa Monica, and West Hollywood have their own distinct rent control ordinances. Unincorporated areas may only be subject to state-level protections under AB 1482.

Financial Impact on Property Owners

Understanding ADU rent control implications is essential for accurate financial projections. Properties subject to rent control may see limited annual rent increases but gain long-term tenant stability. Exempt units offer more flexibility in rent pricing but may experience higher tenant turnover.

Consider these factors when evaluating ADU investments:

• Potential rental income limitations under RSO or AB 1482

• Compliance costs for rent control regulations

• Eviction protection requirements and associated legal costs

• Property tax implications of additional rental units
